How it works
From liquid resin to industrial-grade precision parts. Discover how SLA works, what drives accuracy, and why Raplas machines are engineered for repeatable production.
What is stereolithography?
Stereolithography (SLA) is the original industrial 3D printing technology. A UV laser traces each layer onto a vat of photosensitive resin, curing the material instantly. Layer by layer, the part is formed with exceptional detail, sharp edges, and smooth surfaces – ideal for precision components and repeatable series production.
Production SLA demands consistency. Raplas machines are engineered to keep geometry stable, maintain accuracy across the full bed, and deliver predictable results – job after job.
What you get
- Repeatable accuracy across the entire build platform
- Stable scanning and curing for sharp detail and smooth surfaces
- Faster production without sacrificing edge quality
- Confidence in results across longer builds and larger parts
Built for precision at scale
🪨Granite frame construction
A solid granite frame minimises vibration and thermal movement, keeping the process stable so layers stack accurately over long production runs.
↔ Dynamic 3-axis scanning
Adaptive scanning balances speed and detail – rapid fills where you need throughput, finer control where you need crisp edges and surface finish.
✔︎ HD resolution
High-definition performance across the platform supports complex geometry and fine features without compromising usable build area.
Interchangeable vat system
Switch materials quickly and keep production moving. Rapid-change vats help reduce downtime and make it easier to run multiple materials without lengthy changeovers.
- Zero contamination: Switch materials without complex cleaning cycles.
- Minimised downtime: Change materials in minutes, not hours.
- Material optimisation: Use variable vat sizes to match the job and reduce waste.
